Dear, white, fluffy, floofy Ed ... Can you please tell me why it's necessary for a cat to always eat from the same side of her dish? Mlle. Cassie was meowing at me this morning at 3:15 AM for a refill of her dry food. Her favorite side of the dish was empty, but the opposite side still had kibble in it. What's in her kitty brain that "her" side had to be refilled instead of eating the kibble that was already in the dish?
